Research Interests

Understanding the impact of novel pharmaceutical and exercise therapeutics on the heart failure syndrome.

The focus of my research is to understand the impact of novel pharmaceutical and exercise therapeutics on the myocardium and coronary arteries of the failing heart.  Specifically, current research goals include elucidating new ways to treat both heart failure with preserved ejection fraction (HFpEF; a disease largely unresponsive to current standardized heart failure therapies) and heart failure with reduced ejection fraction (HFrEF) using translational large animal models developed in my laboratory.  Existing projects are utilizing gene therapy and regenerative medicine strategies in a context of preexisting comorbidities (metabolic syndrome) using preclinical swine models (Ossabaw) of experimental heart failure (aortic banding, myocardial infarction).

A further goal of this research is to garner insight into better utilizing exercise as a therapeutic modality in a translational setting of heart failure. I believe that by determining the intensity and frequency of exercise that provides benefits to heart failure patients and the cellular mechanisms underlying those beneficial changes, the laboratory can generate translational windows into new therapeutic opportunities.   My laboratory employs a multidisciplinary approach that integrates systemic physiologic measures with in vitro techniques to study the mechanisms and impact of pharmaceutical and exercise therapies in heart failure including catheter techniques and ultrasound (to measure cardiac and coronary vascular function in vivo), ‘-omics’-based analysis, cannulated vessel preparations, histology, biochemical assays, and patch clamping.  Future goals include translation of our preclinical research models into medical practice with parallel clinical studies, and utilization of physiological inputs from the swine preclinical models to augment computational modeling of heart failure.

CURRENT PROJECTS:

Utilization of multiple translational models (swine) of heart failure with preserved ejection fraction and heart failure with reduced ejection fraction (HFpEF and HFrEF, respectively) for the identification of novel molecular mechanisms involved in the development of heart failure/cardiovascular disease and testing of novel therapeutic strategies in a clinically relevant large animal model. My laboratory has developed both Yucatan mini-pig and obese/diabetic Ossabaw swine models of HFpEF to address these research goals.  Current projects include: 1) development of a transgenic Ossabaw swine model of smooth muscle cell BKCa β-subunit overexpression; and 2) development of an Ossabaw swine model of diabetic HFrEF.

Examination of coronary smooth muscle cell BKCa channels as a primary mechanism mediating impaired vascular/ventricular interactions in heart failure.

Examining the efficacy of a novel gene therapy (myocardial AAV transfection of non-endogenous p90 ribosomal S6 kinases [RSK3] binding domain protein) and mechanism (RSK3-muscle A-kinase anchoring protein [mAKAP] signalosome) for treating the development of heart failure with preserved ejection

Determining the efficacy of a bioabsorbable rhFSTL1*-containing collagen matrix (EpicaPatch), applied to the epicardium overlying the damaged myocardium in infarcted diabetic pigs.

Determination of the molecular mechanisms controlling myocardial fibrosis in a setting of heart failure, including examination of existing and novel imaging techniques in the diagnosis of heart failure and quantification of myocardial fibrosis.

Sex-based disparities in prevalence and development of the heart failure syndrome

Computational modeling of coronary blood flow and systemic vascular stiffness.

Determining the efficacy of DPP-IV and phosphodiesterase inhibition on cardiac remodeling and hypertrophy in heart failure.

Determining the role of increased advanced glycation end product accumulation on increased coronary vascular stiffness and related myocardial oxygen supply/demand imbalance in the development of heart failure with preserved ejection fraction.
